On the other hand, to the inlet of the beam. body 2|, is adjusted the end of a thick seamless tube 23, through which the naphtha contained in the underground storage tank is sucked in.

Said pump is manually operated by means of a handle jointed to the axle thereof.

On the other hand, to the outlet of said pump 20 is fixed an elbow tube 26, provided on the upper part thereof with a cap of the same material. A hinged door 21, for access to the interior of the casing I, is located therein in front of said handle 24.

As may also be seen in Figures 1 and 2, two short thick tubes or pipes 28 start from the upper part of the tank l5, said pipes or tubes having their lower ends screwed to an extension 29 of the plate [4, while their upper ends are screwed to the packing glands 30. 'In turn, two conduits 3| and 32 start from the lower portion of said extensions 29, the outlets of said conduits being connected to the thick tubes 33 and 34 respectively, which, as may be seen from the details of Figures 4, 5 and 6, communicate, by

means of suitably elbowed conduits, with the vertical overflow tubes- 35 and, 3 6, arranged within the transparent containers 6 and 1, respectively.

Also, within said tank I5 are arranged two containers 3'! and 38 (Fig. 1), of similar features, dimensions and weight, said containers being capable of alternative displacements in a vertical direction with perfectly guided movements. For this purpose, said containers are suspended from the rods 39 and 40, said rods passing through the bushings 30, serving as guides, and sliding freely within the bearings or bushings 4I,"and, being connected with said containers by means of the radial arms 42.

'Each of said containers is guided in course of the upward and downward movement thereof by two blades or lugs sliding along two vertical rods 43' bolted to a cross-piece 44, which in turn is rigidly mounted at the end of a central rod 45 screwed by its upper end to a plug 46, integral with the plate l4. On the free end of an extension piece 53, is screwed a valve body 54, the upper portion of which is adjusted in a hermetical manner to the lower end of a tube 55, as may be seen in the detail of Figure 8; said tube is screwed to the lower mouth of a box 56, carrying a further tube 51 which, as, will be explained later, communicates in turn with the interior of the device distributing the pumped liquid to each of the transparent containers, as shown in the details of Figures 3 and 5. Also, within the body 54 are two seat-valves 58 and 59 the first of which, as shown in Figure 2, closes at a given moment the upper or outlet end of the tube 5!, while the valve 59 is capable of closing the inlet end of the upper tube 55; this latter valve is controlled by the action of a small jointed balance-beam 61!, the operation of which will be explained hereinafter.

As may be seen in Figure 3, within the member 3 shown in Fig. 1, two curved conduits BI and 62 are formed, which communicate with the tube 51 for the inlet of the liquid, and which are upwardly closed by the conical seat valves 63 and 64 respectively; said'valves, on being raised by means which will be explainedlaten'allow the admission of liquid to either of the transparent 61, said balance-beam being operated indirectly by the horizontal axle 68. To this effect, Said arm ends in a collar 69 carrying ascrew Hi used for the adjustment of the arm 61 on a horizontal bushing H, arranged within said member 3. As may be seen in the section of Figure 5, said bush ing H encloses the rotation axle 68, serving as a bearing therefor; both the bushing H and the axle 58 operate between two bearings 12 screwed to the external wall and to an intermediate wall or partition of the member 3. As may also be seen in Figure 5, the extreme portion of the bushing H encloses a spiral spring 13 which is arranged between said bushing and the corresponding axle thereof, said spring being maintained in a pressed condition by means of a thin annular bushing 74 fitting by its free ends below the piece H and under one of the bearings 12. Also, to counteract the lateral pressure of said spring, the external bushing H is provided with a conical projection 15 pressing against the bearof the apparatus; the purpose of said valves being to allow the discharge of either of the transparent containers of the apparatus. These valves are actuated upwardly, during their opening movement, by two thin stems or rods (8 jointed to the free ends of two connecting rods 19, each 1 of which is jointed at its intermediate points to two small axles 80 provided withcorresponding nuts. Each connecting rod 79 forms at the back end a toothed sector 8| meshing with a small pinion 82 mounted on the axle 68 mentioned above, and which, as may be seen in Figure 5 is held in position by a latch 83. Said pinion 82 is also integral with a small circular sector 84, for the purpose to be explained later;

Figures 5 and 6 also show that the iron balance-beams 85 and 86 have been arranged on the upper portion of the plate 4, said balance-beams being carried at their centers, on the supports 81 fixed to said plate. Each of the free ends of said balance-beams 85 and 86 engages the pairs of valves "Hi-63 and ll-64 respectively, which consequently are governed by alternative movements, so that while one of them, for example the valve ll opens to allow the discharge of the transparent container 1, the adjacent valve 64 is pressed against the seat thereof, closing the outlet of the curved conduit 62, as may also be seen in Figure 3.

Also, on the opposite end of the axle 68 the bushing H is extended outwardly, as may be seen in Figure 5, carrying-fixed thereto, by means of a screw 88, an oscillating support 89, the front detail of which may be seen in Figure 4. This support carries joined thereto in its lower and internal portion, a counterweight 96 which is situated between said piece and the wall of the member 3, while on the upper and external portion of said support is provided a balance-beam 9| rotating around the rotation axle 92. Said balance-beam 9|, thefront detail of which may also be seen in Figure 4, is provided at its inner portion with an extension capable of fitting in a notch 93 formed in the periphery of the circular sector 94 when the latter is pressed, on its free ends, by a laminar spring 94'. In turn, the circular sector 94 is integral with a toothed wheel 95, as may be seen in the section of Figure 5, which by means of the latch 96 is fixed to the free end of the axle 68.

I'll

A short chain 91 meshes with the toothed wheel 95, the free ends of said chain being joined to the upper. ends of two thin rods 98 (Fig. 12) and 99 which, as may be seen in the details of Figures 2 and 12, are joined in turn to the opposite ends of a balance-beam I09, mounted on a horizontal axle IIiI and fixed to the free end of same by means of a latch or bolt I92. This axle, as is more clearly shown in the section of Figure 8, crosses the chamber 56 throughout its width, said chamber being interposed, as stated above, between free ends of the tubes 55 and 57, allowing however, the free communication between both.

In said Figure 8 it may also be seen that said axle IIlI is mounted on the box 56 by means of two ball-bearings I03 and I94, the latter being adjusted by means of a small metallic plate or disc I55.

Also, on the same axle II'II is fixed a balancebeam IIlIi, the front detail of which may be seen in Figure I I, said balance-beam ending upwardly in a circular sector IIJ'I acting by pressure against the lower portion of an arm I08, one of the ends of which is joined to the pivot I99 carried by the. box 55 (Fig. 8), and the opposite end of which is fixed to a counterweight I III. .In its up ward and downward movements, said arm I08 is guided between the vertical lugs I I I formed on the inner wall of said box. On the other hand,

. the counterweight H9 is joined to a rod H2,

.of the balance-beam I06 are arranged two thin plates H3 and H4, which by means of the bushings II5 are in turn joined to a suitable point of the vertical rods H6 and III, said rods being suitably guided f01 their vertical displacement, by a solid support IIB. Said rods IIS and III are caused to follow the rods 39 and respectively, with which they form a single piece.

By observing Figures 8, 1'0 and 11, it will be seen that on the same axle IIlI a drum H9 is rotatably mounted, said drum being open at the back and having at its periphery a series of openings or orifices I29, the number of which is equal to the number of five-liter batches which may be efiected with a total of fifty liters which is the maximum that may be marked in one delivery.

Within said drum H9 and fixed on the axle IIII is arranged a small gear I2I meshing with asmall pinion I22, the axle of rotation I23 of which is carried by a support I24 fixed to the inner portion of the box 56. In turn, said pinion I22, as may be seen in Figure 14, meshes with a toothed sector formed in the inner portion of a disc I25 which, as is illustrated in Figure 8, is freely mounted on the axle IIII, being internally guided by an internal cavity of the gear IEI. Said disc I25 has joined thereto at an intermediate point, a trigger I26, the purpose of I which'a further cylindrical bushing I28 is arranged, from which a curved disc I29 starts; the periphery of said disc, as may' be seen in the detail of Figure 13, has a projecting tooth I30 tubular extension by means of a small screw I36.

As shown in Figure 8, on the free end of the bushing I28 is screwed a piece I31 which freely passes through a metallic disc I38 fixed on the open front of the box 56. Said piece I37, which is partially hollow, has in the front portion a central perforation to allow the free passage of a detachable key I39 for operating the device indicating the amount of liquid to be delivered.

In the detail of Figure 9, it may also be seen that said key I39 fits between two small jacks I49 which are joined to the inner front portion of the piece I31 and which are pressed by two small laminar springs I4I.

As also shown in Figure 9, on the front part of the disc or dial I38, the different numbers indicating the amount of liquid to be delivered in each operation have been marked, opposite to which an index or pointer I42 is arranged, said pointer being fixed to the front of the piece I31. Also, .on said disc I38, a perforation I43 has been made, through which may be read the numbers of the totalizer I44 (Fig. 8), suitably mounted on a support I45 fixed within the box or casing 56. Said totalizer is operated by a lever I45 which, as may be seen in Figure 10, is joined to the same support I45 and the'upper end of which, ending in the shape of a tooth, fits in the different perforations I29 formed, as already stated, in the periphery of the disc or drum H9.

The device for the expulsion of the air contained in the transparent containers during their filling operation and for the overflow of the excess liquid has been illustrated in Figure '7. Said figure shows the tube 35 which, similarly to the tube 35, reaches to the upper portion of the transparent containers 5 and I respectively, which, as already stated, are upwardly closed by the plates 8. I

As may be seen, in the upper part of each of said plates 8 is formed a vertical extension I41 which carries in its innerportion a screwed piece I 48 which is hermetically adjusted relatively to said plate by means of the packings I49. In turn, on the lower end of said tubular piece is screwed the threaded portion of the tube 35.

Figure 7 also shows that on the sides of the tubular piece I48 are formed a series of rectangular openings I which allow the passage of the excess liquid, which will freely empty into said tube 35, as indicated by full line arrows.

Within the tubular piece M8 is screwed a plug I5I which also may be adjusted hermetically re1atively to the former by means of a packing I52, leaving a small free space on the border of the central tube 35. Within saidplug, a cylindrical chamber is formed, said chamber I53 communieating with a small vertical tube I54 fixed on the lower part of same. The central chamber I53 communicates, by means of suitable openings, with two other concentrical chambers I55 and I56 formed between the plug I 5| and the bushing I48, and between the latter and the extension I I'I of the plate 8, respectively. Finally, the external chamber I55 communicates, by means of a thin conduit with a small tube which, as may be seen in Figures 1 and 6, is joined by means of a T-piece, with the similar tube starting from the opposite transparent container, and with an outlet vertical tube I58 reaching to the lower plate 4, to which it is fixed by means of a threaded bushing I59 and counternut I60.

In Figures 5 and 6 it may also be seen that over the front of the member 3. is adapted a piece I6I provided with a small spy-glass or the like I62 through which the outlet of the liquid may be observed, and to the lower portion of which a piece I63 is fixed; a thick tube I64 for the outlet of the liquid starts from said piece I63, said tube having on its free end the corresponding delivering hose screwed to same.

Said piece 163 constitutes the body or chamber of the float; a floating cylinder I65 is fixed on the free end of an arm I66 rotating about a horizontal axle I61. A curved projection I68 is formed on said float, which on being raised from its position by the lifting of said float, acts against the circular sector 84 which, as already stated, is integral with the pinion 82 mentioned above. In its upward and downward movements, the float I65 is guided by two small stems I69 fixed on the inner wall of the member 3.

-'As may also be seen in Figure 5, the inner portion of the same member 3 has a small steel spring or the like I10 operating by pressure against the free end of the horizontal axle 68, holding same against a seat formed by the projection and bearing 1I. At the entrance of the conduit I64 and adjusted by screws or any other means, is a metallic sheet I1I in the shape of a partition, the object of which is to prevent that, from the outside, the arm I66 of the float may be caught, or to prevent any other fraudulent manipulations.

As may be seen in Figures 1 and 2, at one side of the body 54 a plug I12 has been screwed, said plug being provided with a small horizontal perforation from which'extends a small thin tube I13 which, as will be seen later, is intended for the return of the liquid left in the transparent containers to the feeding tank. Said tube com municates with a further small tube I14 which, by means of a counternut I15 is coupled to the plug 46 mentioned above, in which a series of small perforations I16 has been made for the overflow of the liquid contained in said tube.

Said tube I14 is in direct communication With the vertical tube I", which as may also be seen in the detail of Figure 5, presents in its upper part a funnel I18 for collecting the liquid that may have filtered through the valve-axles.

As may be seen in Figure 2, a further small tube I19 empties also into the same plug 46, said tube collecting the liquid which may have filtered through the lower valve device.

Finally, as may be seen in Figure 2, within the tank I6 an overflow tube I80 has been adapted, said tube assuring a constant level of liquid within said tank when the apparatus is not being used. The excess over the level of said liquid returns to the feeding tank by means of the tube I8I communicating directly with the vertical tube I9.

The operation of this type of apparatus is very simple and is effected in the manner explained below When -the consumer asks for a determined amount of liquid, the operator will be compelled, in order to carry out the pumping, to place the indicating pointer I42 on the division of the disc I38 corresponding to the quantity asked for, as is illustrated in Figure 9. To effect this, he will operate the detachable key I39 which will be placed over the axle IOI, as may be seen in Figure 8, and will rotate the piece I31 until said pointer marks on the disc I38 the number of liters desired by the consumer. It will be observed that, on rotating said pointer I42, the curved disc I29 will also rotate, the projecting tooth I36 thereof will lift the arm I08 to which is fixed the counterweight I I6 and the rod I I2, and this latter rod will in turn cause, as shown in Figure l, the lowering of the valve 59 by means of the balancebeam 60.

Assuming, for example, that the consumer wants 15 liters, the operator will actuate said key I39 until the pointer I42 coincides with the number indicating this quantity on the disc I38. In effecting this operation he will have caused the rotation of three teeth of the pinion I32,

which is equal to three deliveries of five liters.

It must also be borne in mind that the jacks I46 only allow the pointer to move forwardly.

If the lever 24 is thereupon actuated, the pump 26 will be operated which, by means of the suction pipe 23, will draw the naphtha from the deposit tank, causing same to pass through the filter 22 which, as already stated, is constituted by two gauzes of different mesh, said filter retaining all the impurities carried by the liquid. By the action of said pump 20, the liquid will then be forced through the pipe 26, emptying into the tank I6 of air displacement.

The liquid entering said tank, will be subject ed to a determined pressure by the action of the pump 25, and after displacing the air, will rise,

through the action of the same pressure, through the pipe 5|, causing the lifting of the corresponding retention valve 58, shown in Figure 2, then passing to the valve body 54. As the valve 59 (see Figure 1) has been lifted in the previous operation, that is to say, when marking the amount of liters to be delivered, the liquid forced by the feeding pump will pass through said valve 59 and rising through the pipes 55 and 51 will reach the valve chamber represented in Figures 3 and 5.

Assuming that at this moment the valves 65 and 66 are in the position represented in said Figure 3, that is to say, covering the entrance to the conduit 6|, the liquid which has arrived through the pipe 51 will be compelled to rise through the conduit 62, and after lifting the valve 64 will enter the transparent container to be charged, which in this case will be the transparent container 1, the discharge valve 11 of which will be closed, since same, as may be seen in Figure 5, operates in counterposition with said valve 64 by the action of the balancebeam 85.

Now, the liquid entering this transparent container will, fill same completely, and the liquid entering later will overflow through the upper part of the central tube 36, as illustrated by the continuous arrows of Figure '7, while the air bubbles carried in suspension by the liquid will escape in the direction of the dotted arrows, being expelled to the exterior after passing through the tubes I51 and I58, shown in Figures 1, 6 and 7, thus obtaining the exact measure of. the liquid.

In turn, the liquid which has overflown to the interior of the central tube 36, will pass through one of the curved conduits represented in Figures 4 and 6, pouring into the tube 34 and after passing through the conduit 32 will empty into the movable container 38, as shown in Figures 1 and 2.

Said container 38 as Well as the similar container 31 have been constructed in such manner that they operate by gravitation when they are full with the determined quantity of liquid, in such manner that when said quantity is emptied into said container .33 it will descend by its own weight, carrying in its fall the rod 40 and its corresponding member I I1, and thus causing the rotation of the balance-beam I96 to which it is joined by its corresponding connecting rod I I4. The reversing of this balance-beam, which is effected every time one of the transparent containers has been completely filled, transmits to the apparatus the necessary force for governing the different movements of the movable elements.

When the movable container 38 has fallen to its lower position, the fixed stem 50 causes the rising of the corresponding valve 48, in such manner that the liquid contained in same will come outthrough the opening 49, falling into the conduit i1 and returning to the storage tank through the tube I9.

Also, when the lowering of the container 38, by the action of the excess liquid in the transparent container 1, takes place, with the corresponding rising of the opposite container 31, this will cause the rotation of the balance-beans I96 which, as may be seen in Figures 1, 2, 8 and 11, is fixed to the horizontal axle IflI. The rotation of this latter axle causes the rotation of the second balance-beam Ifli! represented in Figures 2 and 12, which by means of the rods 98 and 99 and the chain 91, actuates the toothed wheel95 which, as may be seen in Figures. 2, 4 and 5, is intended to reverse the position of the valves 65 and 66.

It should be borne in mind that the different movements of the governing elements of the apparatus take place in three stages, which are effected during the reversion of the movable conwhich acting on the toothed sectors 8i will rotate the arms 19 in opposite directions, causing, by means of the stems 18 the lowering of the charge valve 11 of thetransparent container to be charged, that is to say, the transparent container 1, which will thus occupy the position indicated in Figure 6, having thus completed the first phase or stage of the operation. As said stems act on the center of each of the valves ,16 and 11, they allow the lifting and lowering thereof in a smooth manner, thus increasing their durability.

The second stage, that is to say, the closing of the charge valve of the transparent container to be discharged, which in this case would be the transparent container 6, is effected by means of the circular sector 94 which acting by means of the notch 93 as may be seen in Figures 4 and 5,

. will carry in turn the piece 9| and the similar sector 84 which, as has been stated, is integral 7 with the former.

The purpose of the float I65 is to lock, by means ofv the tooth or upper projection I68 the movement of the sector 84 while the transparent container to be discharged has not been completely emptied, thus preventing a new delivery until the previous one is completed. When the liquid has finished passing through the tube I64, said float will descend and the upper projection I68 will unlock the sector 84 allowing then the corresponding reversal of. the upper valve and other movable elements of the ap-- paratus.

On the other hand,-as the valves 63 and 64 of the transparent container to be charged remain lifted for a space approximately equal to two mm. during said charge, which is obtained by means of the balance-beams 85 and 86 illustrated in Figures 5 and 6, the excess liquid in each of the transparent containers may be freely discharged up to the level of the piece I12 which, as already stated, is provided with a narrow orifice from which starts a thin overflow tube I13 discharging indirectly into the feeding tank. In this manner, the excess liquid of the transparent container leaves it by said orifice, discharging in a constant manner through the said tube 513, the similar member I14, the tank I5 and the return pipe I9, the apparatus thus remaining safe from any contingency.

During the second stage, the registering of the delivery is effected in the totalizer I44, and at this moment the pointer I42 indicating the quantity of liters on the disc I38, recedes into a division corresponding to the five liters. This is obtained by means of the jacks I26 and I21 which, as is understood, simultaneously actuate said indicating pointer I42, and the lever I46 which acts on the totalizer I44.' The second one of said jacks, that is to say, the jack I21, as may be seen in Figure 11, is actuated by the balancebeam IDS, when the latter operates from right to left, while the first jack, that is to say, the jack I Ziiis not directly operated by saidbalance-beam, but in an indirect manner, every time said balance-beam: operates from left to right. In effect, thejack I24 is moved by means of the gear I21 fixed to the axle IIIII, and by means of the pinion I22, the latter of which, as may be seen irithe detail of Figure 14, acts on the toothed sector, formed within the disc I25, which while rotating carries said jack.

1 As already stated, the drum II9 is provided on its periphery with rectangular openings I corresponding in number to the five liter deliveries which may be effected with liters, which is the maximum quantity that may be marked in one delivery. Over said openings, the free ends of the jacks I26 and I21 fit; said jacks in their dragging action will cause said drum II9 to recede with each five liter delivery, and in turn .wil1 recede the pointer I42 by the amount of the quantity indicated, V

In effechthejack I33, as may be seen in Figwe 10, is jointed'directly to the internal portion of the drum I I9 and thus will be carried by same, compelling theteeth I32 to accompany same in each of their corresponding backward motions to the different five liter deliveries; on the other hand, as said teeth form a part of the bushing IZILand the latter is integral with the piece I31 and pointer I42, said pointer will efiect a backward motion with each five liter delivery until it reaches zero. In the zero position, the arm I08 of the counterweight, will fit in the notch I3I of the disc I29, which is illustrated in figure 13,

the said drum, actuates the totalizer I.

thus lifting again thevalve 59 which will render impossible any fraudulent manipulation or delivery.

In Figure 10 it may be seen that the drum III] in each position is retained by the lever I46, the upper end of which, ending in the form of a claw, fits in each of the openings I29 thereof; said lever, apart from acting as a retention jack for In fact, as may be seen in Figure 8, every time the upper end of said lever is raised over the drum II9, rotating about its point of articulation with the support I45, the opposite end of which the support pushes upwardly the small actuating leverof said totalizer, thus marking another unit of five liters delivered by the apparatus, said indication being perfectly visible from outside, through the opening I43 formed in the disc I38. One of the special advantages of this type of apparatus the operation of which has been explained, resides in the elimination of all kinds of packing glands, using instead a system of valveaxles which allows a light operation.

Also, shouldany loss of liquid be produced along said valve-axles, same would be easily collected by the funnel I18 shown in Figures 2 and 5, and by the small tubes IIIand I14, which would discharge it into the piece 46,,together with the liquid discharged by the tube-I13 stated above; this liquid will come out by the narrow orifices I16 provided in the interior of said piece, to fall within the tank I5, and pass from said tank to the-storage tank, through the lower tube I9.

The lubrication of the apparatus is effected by means of a suitably placed device, not shown, which insures the regular access of the lubricant to all the operating parts.

The operation in the manner explained, is quite evident and requires no further explanation to those skilled in the art.

'It'is evident that the invention is capable of several modifications in detail and construction, without departing from the scope of the invention as clearly set forth in the appended claims.
